Impact of pregnancy on maternal AIDS.

Objective: To assess the impact of pregnancy on maternal acquired immunodeficiency syndrome (AIDS) among tribal women in India.

Study Design: From February 1992 to February 1996, 71 tribal women from Manipur, India, with AIDS (Centers for Disease Control stage iii/iv), matched for age, parity, CD4 lymphocyte count and demographic characteristics, were recruited into a prospective study. Thirty-two (49%) of these women were pregnant (8-10 weeks) (group A) and 38 (51%) nonpregnant (group B).

Results: Pneumocystis carinii pneumonia followed by miliary tuberculosis and wasting disease were the most common AIDS-defining illness and cause of maternal death in both groups. A total of 28 (39%) women died as a direct result of their AIDS-defining illness; 10 (27%) of them were among the nonpregnant women as compared to 18 (56%) deaths among the pregnant women (P = .17, odds ratio 3.7285, 95% confidence interval 1.23, 11.58). Three (16%) of these 18 deaths occurred within 14 weeks of an uneventful first-trimester medical termination of pregnancy. Thirteen women (41%) died undelivered at 30-34 weeks' gestation, and two died within 3 weeks of delivery. Fourteen (44%) women vaginally delivered 14 preterm infants, between 28 and 35 weeks' gestation. Eleven of these infants died within six weeks; nine deaths were a direct result of prematurity and clinical diagnosis of an AIDS-defining illness. The mean survival time was 9.72 months for the pregnant women and 22.6 months for the nonpregnant women (P = .066).

Conclusion: Pregnancy increased maternal and fetal mortality in these AIDS-infected women.
